[0039] FIG. 3 is a sectional elevation view of the upper part of the device for diffusing volatile substances of the present invention, according to a third embodiment.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0040] As shown in FIG. 1, the device for diffusing volatile substances comprising a container 1 to house a liquid containing the volatile substances, a capillary element 2, such as a wick that is partially housed in said container 1, so that the liquid from the container 1 is moved by capillary action to the end of the capillary element 2 located outside the container 1.

[0041] The device for diffusing volatile substances also comprises a perforated element 3, for example, a grid, through which the volatile substances diffuse into the environment, and a piezoelectric element 4, such as a piezoelectric disc, which is in contact with said perforated element 3 and with the capillary element 2.

[0042] Said piezoelectric element 4 vibrates, transmitting the vibration to the capillary element 2, to increase the evaporation of said volatile substances.

[0043] Furthermore, the diffusion device also comprises an elastic element 5, on which said piezoelectric element 4 is mounted, said elastic element 5 being attached to said housing 6 surrounding said container 1, according to the embodiment shown.

[0044] It should be noted, however, that the elastic element 5 could also be attached directly to the container 1. Furthermore, the attachment of the elastic element 5 to the container 1 or to the housing 6 can be performed in any suitable way.

[0045] Said capillary element 2 defines a central longitudinal axis (indicated A in the figures), and said elastic element 5 is advantageously a body rotating around said central longitudinal axis A of the capillary element 2, and having a geometry that allows its deformation when it is subjected to pressure.

[0046] Said elastic element 5, which is preferably a bellows made of an elastic material, comprises a hole 7 which is located centered with respect to said central longitudinal axis A of the capillary element 2, wherein said piezoelectric element 4 is mounted.

[0047] To facilitate the transmission of vibration from the piezoelectric element 4, it comprises a central deformation 8, which defines a cavity on its face facing the capillary element 2, as can be seen in the figures.

[0048] The geometry of said elastic element 5 allows a deformation equivalent to the sum of the manufacturing and assembly tolerances of the elements that make up the device, which characterize the quality and quantity of nebulized fluid. In turn, this elastic element 5 maintains an adequate pressure to maintain the quality and quantity of diffusion within the required parameters.

[0049] According to the first embodiment shown in FIG. 1, the side wall of said bellows 5 is curved.

[0050] In FIG. 2 a second embodiment is shown, in which the side wall of said bellows 5 defines two sections that form an acute angle.

[0051] For its part, FIG. 3 shows a third embodiment, wherein the side wall of said bellows 5 comprises a plurality of folds, the width of the bellows 5 being smaller towards the piezoelectric element 4 than towards the container 1.

[0052] These designs provide different responses to the pressure exerted by the capillary element 2 on the piezoelectric element 4.

[0053] Although reference has been made to specific embodiments of the invention, it is clear to a person skilled in the art that the described device for diffusing volatile substances is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by others technically equivalent, without departing from the scope of protection defined by the appended claims.
